i This invention per ains to rail a roll ng stock, and more particularly to improvements in car trucks, The inventionf is d1rected especially to improving trucksofthe quick wheel change type. 1

"Themain purpose of the" invention is to provide a car truck in which the'side frames are normally interlocked with:'theispring plank; said plank beingvertially movable relatively to the side frame and beingadapted 4 to lift the sidefra'mes" withtheplank after -the plank has been elevatedtoapredeter- 'mined eXtent rel ative1y to the side frames. This invention will facilitate thedetachment of the side frames and! enable'the removal ofthe wheels, to'be expedited: i I

A further obj ect' fis toifurnish fsidej frames of improved form, having overhanging ledges or walls, designed to be engagedby thespring V plank to enable the vplank while'being ele- J med, to lift-the side-frames during the course of the; elevation, and only" after, theplank has been raised to apredetermined degree relatively to the side framen The invention is illustrated inthe accompanying drawings, and will'now bedescribed i with reference thereto. Referring'to'the drawings,
